Abstract

Nuclear energy, as one of the crucial high-energy-density clean energy sources, is inherently associated with safety concerns regarding radiation dose throughout its development and application. The evolution of distributed power markets has rendered the calculation of dose rates for small reactors a focal point of research. This study employs uncertainty-based particle transport calculations and burnup calculations using the matrix exponential method. A Rigorous 2-Step (R2S) program is developed for the coupled neutron-high-energy gamma-ray transport in a multi-physics framework involving criticality, burnup, and activation processes. The correctness and accuracy of the algorithm are verified against the internationally recognized ITER shutdown dose rate benchmark. The research findings demonstrate that the R2S program aligns well with numerical solutions provided by various authoritative international institutions for FDS, SWIP, Jakhar and CCFE programs in benchmark calculations. Consequently, the R2S algorithm developed in this study proves applicable for dose rate numerical calculations in small modular solid-state nuclear energy systems, offering robust data support for the safety assessment of advanced nuclear power systems.
